Temporal coupling between postural and voluntary components of the task. A. Median values of correlation between CoM and fingertip velocity profile in EO and EC conditions for controls and subjects with PD. Values equal to 1 indicate a perfect correlation. B. Median values of the individual differences in correlation between the EC and EO conditions for CTR and subjects with PD. Zero on the ordinate represents no effect of eye closure. * indicates significant difference (p<0.05) in the effect of eyes closure between the groups.
